NABTEB Light Vehicle Body Repair study plan

NABTEB Light Vehicle Body Repair · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Workshop Safety, Tools and Equipment & Materials, Fasteners and Body Construction

  • List and explain the purpose of at least ten items of personal protective equipment used in a body repair workshop, stating the specific hazard each controls

  • Identify by name and function at least fifteen hand and power tools used in panel work, including hammers, dollies, spoons, slappers, grinders and reciprocating saws

  • Demonstrate safe lifting, jacking and supporting of a light vehicle using axle stands and wheel chocks, and describe the consequences of each unsafe practice

  • Classify at least eight automotive body materials (mild steel, high-strength steel, aluminium, plastic, glass, rubber, sealant, composite) and state one repair implication for each

  • Distinguish between bolted, riveted, welded and adhesive joints, and name the common fastener types with their thread or size designations

Your checkpoint

A hand-written or typed workshop safety and materials reference sheet of at least 40 items, cross-referenced to the hazard or repair implication, self-tested to 90% recall

Week 2

Body Panel Removal, Replacement and Alignment

  • Describe the correct sequence for removing a bolted front wing or door, including disconnection of electrical, trim and seal components before fastener release

  • Explain gap and flushness measurement using feeler gauges and panel gap gauges, and state typical tolerance values for door, bonnet and wing shut lines

  • Identify the locating, adjustment and shimming points on a door hinge and describe how to bring a misaligned panel back into specification

  • Outline the procedure for temporary and permanent replacement of a welded-on panel, naming the cutting, preparation and joining steps in order

  • Explain how to protect adjacent panels, glass and wiring during removal and refitting operations

Your checkpoint

A written step-by-step removal, replacement and alignment procedure for one bolted panel and one welded panel, each with a tool list, safety notes and a gap tolerance table

Week 3

Panel Beating, Shrinking and Stretching

  • Explain how panel deformation occurs under impact and identify the direct, indirect and elastic damage zones on a damaged panel

  • Demonstrate, in description or practice, the correct use of hammer and dolly for planishing, and distinguish it from roughing-out and finishing blows

  • Describe the shrinking methods available (heat shrinking, shrinking hammer, shrinking disc) and state when each is appropriate

  • Explain stretching of metal, the causes of over-stretched panels, and the technique for correcting a stretched area before filling

  • Identify signs of work-hardening and describe how to anneal or relieve stress in steel and aluminium panels

Your checkpoint

A practical or simulated panel beating log recording at least five damage scenarios, the technique chosen for each, and a labelled sketch showing hammer, dolly and blow direction

Week 4

Welding, Brazing and Joining Techniques

  • Compare MIG/MAG, TIG, oxy-acetylene and resistance spot welding in terms of application, heat input and suitability for thin body panels

  • State correct machine settings, wire or filler selection and gas choice for 0.8 mm mild steel and for aluminium body sheet

  • Describe the brazing process, its filler and flux, and explain why brazing is preferred over fusion welding on some modern high-strength steel sections

  • List the weld defects that cause rejection (porosity, undercut, lack of penetration, burn-through, spatter) and their probable causes

  • Explain distortion control measures during welding, including stitch welding, backing, clamping and heat management

Your checkpoint

A welding process comparison chart covering four processes plus a defect-cause-remedy table of at least eight defects, with settings recorded for one practice coupon

Week 5

Body Filler, Preparation and Surface Finishing & Spray Painting, Refinishing and Colour Matching

  • Prepare a bare steel or repaired panel through the correct sequence of grinding, cleaning, degreasing and application of etch primer or epoxy primer

  • Apply body filler in thin, correctly catalysed layers using a spreader, then shape and finish it with a flexible abrasive block to a feathered edge

  • Describe the grades of abrasive paper and their correct use at each stage from shaping through to final flatting before topcoat

  • Explain the composition and function of primer, sealer, basecoat, clearcoat and hardener, and state the mixing ratio principle for two-pack products

  • Identify the main spray gun types (suction, gravity, HVLP) and explain setting of fluid needle, fan pattern and air pressure for a full panel coat

Your checkpoint

A surface preparation and finishing specification sheet listing each stage, abrasive grade, product type, mixing ratio and inspection check, plus a completed practice panel with feathered filler edge

Week 6

Spray Painting, Refinishing and Colour Matching

  • Explain how colour is matched using the vehicle paint code, variant chips and spray-out cards, and describe the procedure for a blend panel

  • Describe the causes and prevention of runs, sags, orange peel, dry spray, blushing and fisheyes, and how each is corrected

  • Outline masking procedure for a part-panel repair, including reverse masking, soft-edge techniques and protection of glass, trim and gaps

  • State the environmental and health controls required in a spray booth, including extraction, respirator type, solvent storage and waste disposal

  • Describe the polishing and defect removal sequence from compounding through to final glaze, and the curing or baking conditions required

Your checkpoint

A colour matching and defect diagnosis report: one documented spray-out comparison with a blend plan, plus a table of six paint defects with cause, prevention and correction

Week 7

Vehicle Glazing, Trim, Seals and Accessories & Frame, Chassis and Structural Damage Assessment

  • Describe the removal and refitting of bonded and rubber-sealed windscreens, including the cutting method, primer, adhesive bead and safe-out time

  • Explain how to remove and refit door trims, weatherstrips, badges, mirrors and other accessories without damaging clips or painted surfaces

  • Identify the types of vehicle body construction (body-on-frame, monocoque, spaceframe) and explain how each affects damage assessment and repair authority

  • Describe how to measure a damaged structure using datum points, centre-line gauges, tram gauges or a measuring system, and interpret the readings against specification

  • Explain the concept of a crumple zone and a designated repair or replacement zone, and state when a structural section must be replaced rather than straightened

Your checkpoint

A glazing and trim job card for one vehicle plus a structural damage assessment report for a simulated collision, including measurement readings, a verdict on straighten or replace, and a justification
